I just figured out why cfg.lua doesn't move any frames...
healer layout is problem. try healer layout. then cfg.lua will working.
but you should have edit some lines in core.lua and lib.lua.
(for customizing, or localizing)

now here's question. how can I make raid frame bigger? not scale, real pixel size. I was looked every codes I really do. but I don't know yet.

For those of you having a problem with the latest release, it's a folder within a folder. First folder should be "oUF_Qulight v0.1.3b", within that folder is "oUF_Quilight" which is the folder you extract to your addon folder
